I'm prepairing my own enclosure for AudioMoth. I've used a light waterproof IP box. I put a little porexpan inside to fix the Audiomoth in a specific and adecuate position not moving. Then, I put the lid with a tiny hole where the microphone is situated. I'm here for asking for any ideas to cover that because I couldn't find an acoustic waterproof cloth. It's for personal use to study the environment of my house (I live in the field) and in the city, in my relatives houses , so I'm going to install and retire it always the the next morning (not more than one day out). So, any recommendations? As a subsitute for the «authentic acoustic waterproof cloth»... I suppose something thin could work well, like paper film or somethig, but I don't know how the audio quality could be.
